Carotid angioplasty, or balloon angioplasty, is used to dilate (open) the carotid artery narrowed by carotid artery disease.
A long, thin flexible tube (catheter) with a balloon tip is inserted into an artery in the groin. Guided by X-ray and a contrast "dye," the tube is threaded to the site of the narrowed carotid artery. Once in place, the balloon is inflated and pushes the plaque against the artery wall.

The stent is placed after the angioplasty is performed. A stent is a tiny, mesh or lattice-like coil often made of stainless steel. The stent is mounted on the catheter and expanded with a balloon. This presses the stent against the artery wall and helps prop open the blood vessel. The stent is permanent and provides support for the artery to remain open.
There is some risk with every procedure. The risk varies with each person, depending on the extent of the carotid disease and the type of procedure. Although rare, bleeding, reaction to contrast dye, kidney failure, blockage of an artery, a transient ischemia attack (TIA) or stroke may occur. These problems may require additional surgery. Your surgeon will discuss with you the benefits and risks of your surgery.
Surgery is sometimes postponed due to another patient needing emergency surgery, or if you develop a fever, sore throat or cold. You are told of any delay as soon as possible. Surgery is postponed only when absolutely necessary.
